AN INTRODUCTION TO RAID

2.1 RAID VOLUMES

RAID technology allows one or more disks to be combined into a logical volume which provides greater performance and/or protection than standard single disk drives. These volumes, also known as RAID Groups, appear like regular disk drives to the operating system and can be partitioned, formatted and used just like any other normal disk. The creation and necessaries calculation of the RAID is hidden from the operating system.

There are several different methods of combining disks. Each method is referred to as a RAID “level” such as RAID Level 1, or RAID 1. The details of each level are summarized below and detailed in the following sections.

RAID LEVEL CONFIGURED

AS

ADVANTAGES DISADVANTAGES

0 Striped Excellent performance

All of the Hard Drive disk space is available to use

No data protection

1 Mirrored Excellent data protection Space available is divided by half

10 Mirrored Striped High performance

Excellent data protection

Space available is divided by half.

Required 4 disk or more

5 Parity RAID Good data protection, Good

Proformance

Some performance degradation for writes.

Space avalible is total number of hard drive space minus one hard drive space

Required 3 disk or more

Combination Concatenated Good performance

All of the Hard Drive disk space is available to use

No data protection

Single Drive / Segment Contiguous Same as single disk Same as single disk

2.2 SEGMENTING DISKS

For increased versatility, the TR4M utitly, SATARAID5 software, allows individual disks to be divided into smaller segments which can then be combined into different volumes. As an example, if a user has one set of data that must be protected at all costs, another set of data which should be protected at reasonable cost and another set that doesn’t need any

protection at all; the user can divide three disks into sections as shown in Figure 1. The yellow regions define the high security volume, the green section is the middle security volume and the light blue shows the unprotected area.

(7)

Figure 1: Dividing Disks into Members 2.3 RAID LEVELS IN DETAILS

2.3.1 Disk Striping (RAID 0)

Striping is a performance-oriented, non-redundant data mapping technique. While Striping is discussed as a RAID Group type, it is does not provide any fault tolerance. With modern SATA and ATA bus mastering technology, multiple I/O operations can be performed in parallel, enhancing data throughput. Striping arrays use multiple disks to form a larger virtual disk. The figure below illustrates a three-disk stripe set. Stripe one is written to disk one, stripe two to disk two, and so forth. RAID 0 sets can be comprised of two, three, or four drives. If the sizes of the disk segments are different, the smallest disk segment will limit the overall size of the RAID Group.

Stripe2 Stripe5 Stripe8 Stripe11 Stripe0 Stripe3 Stripe6 Stripe9 Stripe1 Stripe4 Stripe7 Stripe10

2.3.2 Disk Mirroring (RAID 1)

Disk mirroring creates an identical twin for a selected disk by having the data simultaneously written to two disks. This redundancy provides instantaneous protection from a single disk failure. If a read failure occurs on one drive, the system reads the data from the other drive. RAID 1 sets are comprised of two drives, and a third drive can be allocated as a spare in case one of the drives in the set fails. If the sizes of the disk segments are different, the smallest disk segment will limit the overall size of the RAID Group.

Block 0 Block 1 Block 2 Block 3 Block 0 Block 1 Block 2 Block 3

2.3.3 Disk Mirroring and Striping (RAID 10)

(8)

8

The data is written to RAID Group A, which is mirrored (RAID 1) and provides data redundancy. Alternating blocks of data are then striped across another RAID 1 mirrored set, shown as Set B in the figure above. This provides improved speed.

Under certain circumstances, a RAID 10 set can sustain multiple simultaneous drive failures. For example, Group A and Group B can allow one Hard Drive in their respective group to be fail simultaneously.

2.3.4 Parity RAID (RAID 5)

Parity or RAID 5 adds fault tolerance to Disk Striping by including parity information with the data. Parity RAID dedicates the equivalent of one disk for storing parity stripes. The data and parity information is arranged on the disk array so that parity is written to different disks. There are at least 3 members to a Parity RAID set. The following example illustrates how the parity is rotated from disk to disk:

Parity RAID uses less capacity for protection compare to RAID 1 and RAID 10 and is the preferred method to reduce the cost per Gigabyte for larger installations. Mirroring requires half of the capacity to protect the data whereas the above example using three hard drives only requires a one-third of the capacity. The additional required capacity decreases as the number of disks in the group increases (i.e., one-forth for four drives or one-fifth for five drives).

In exchange for protection, Parity RAID degrades performance for write operations. The write performance is slower compare to RAID 0 is due to each write performed need to calculate the parity. However read performance will be increase using Stripping Method.

2.3.5 Concatenation (Spanning)

The Concatenated mode combines multiple disks or segments of disks into a single large volume. It does not provide any data protection or performance improvement but can be useful for utilizing leftover space on disks. Concatenation allows the segments that make up the volume to be of different sizes.

2.3.6 Contiguous (JBOD/Single Drive/Segment)

The single drive is a virtual disk that can either be an entire disk drive or a segment of a single disk drive. Single drive is the “Contiguous” configuration option when creating RAID Groups (or sets) in the SATARAID5 software.

(9)

2.4 RAID VOLUME STATUS

A RAID volume can be in any one of the following statuses.

STATUS MEANING

Good All disks are currently functioning as normal. Reduced

For RAID levels that provide data protection, one or more disks have failed but the data is still available via the RAID protection. The failed disk should be replaced as soon as possible to avoid loss of data.

Rebuilding A failed disk drive has been replaced and the data is being regenerated on the replacement disk. When complete, the RAID Group will return to Good status. Resynchronizing An error has occurred and the RAID level is being regenerated. When complete, the

RAID Group will return to Good status. Failed

One or more disks have failed and RAID cannot regenerate the data. The minimum number of failures required to reach this state depends on the RAID level:

z RAID 0, Concatenated, Contiguous: Single disk failure. z RAID 1, 10, and 5: Two disk failure.

SATARAID5 ARRAY MANAGER

4.1 OVERVIEW

The SATARAID5 Array Manager is the Graphical User Interfaces (GUI) which allows you to create and manage RAID volumes. The Manager divides into two sections, RAID Groups Windows and Device Configuration Windows, as seen below.

The RAID Groups window identifies Host Bus Adapters and configured RAID Groups. For systems with more than one Silicon Image Host Bus Adapter installed, you can switch between cards by selecting the desired card in the RAID Groups Window.

When a controller is selected, the RAID Groups currently defined on that controller are also shown in the RAID Groups Window. Selecting a specific RAID Group will highlight the segments associated with that volume in the Device

Configuration Window.

The Device Configuration window identifies all physical drives and their partitions.

Throughout the Manager, different colors are used to indicate the different status. The status can be identied as follow:

COLO R

STATUS

Green Good.

Yellow Warning. The service degraded and action required. Red Failed.
